DISH-WASHING MACHINE.

Speciication of Letters Patent.

of which the following is a specification.

Our invention relates to improvements in dish washing machines, thel object of the invention being to provide improved mechanism for automatically washing a plate or dish, and then carrying'the plate or dish out of the washing tank onto a delivery platform.

A further object is to provide an improved dish washing machine which automatically permits the dishes to fall into operative position between two Sponges or other washing means, and which, at the proper time, separates the Sponges, removes the washed plate, and permits a dirty plate to fall into place to be washed.

A further object is to provide an improved dish washing machine which is entirely automatic in its operation, and which, through the medium of a continuously turning driving gear, transmits motion to the several mechanisms, whereby the plates are washed and delivered, hence simply requiring the attention of some one to supply the plates and another to remove them.

With these and other objects in View, the invention consists in certain novel features of construction and combinations and arrangements hereinafter described and pointed out in the claims.

top and bottom and supported by legs 2,

the latter connected by transverse bars 3 as clearly shown. (Dm-the bars 3, bearings 4 are located and support@ horizontal shaft 5. A face gear 6 is secured -on shaft 5 and meshes with a gear 7 secured to a shaft 8, the latter vertically disposed and supported in bearings 9 and 10, respectively, the former secured to casing 1 and the latter supported on a cross bar 3.- by a pinion 11 on a driving shaft 12, the latter supported in bearings 13 and in line with a second driving shaft 14. These driving shafts have beveled gears 15 .at their adjacent ends supported in a boxing 16, and driven by a beveled gear 17 on a stub 18 also mounted in said boxing. This stub 18 has a crank arm 19, so that it may be manually revolved or' may be driven in any other approved way.

On shaft 12, above pinion 11, a gear 20 is secured and meshes'with a gear 21 on a vertical shaft 22. This shaft 22 extends up through the bottom of a'washing tank 23 and on its upper end, a sponge 24 is secured in any approved manner.v Inline with shaft 22 and directly above the shaft, is a shaft 25. These shafts 22 and 25l are connected by collars 26 located in grooves bars 28, and these cross bars 28 have reduced ends 29 which move in longitudinal slots 30 in boards 31 secured to the sides of casing 1 andv extending above and below the same as clearly shown. The upper shaft 25 is provided at its lower end with a sponge or similar cleaning device 32, and at its upper end projects through a 'fixed cross bar 33. A gear 34 secured to the shaft 25 is Gear 7 is drivenl 27 with cross ferred to, so that when the crank arm 19 is d turned, shafts 25 and 22 will be revolved in opposite directions to thoroughly clean a plate 36.

It is to be understood, of course, that the tank 23 will contain a cleansing liquid, preferably soapy water, to the necessary level, and that tie Sponges with their plate are normally below the level of water, but are elevated as will be hereinafter explained.

@n gear wheel 6, a crank arm 87 is adjustably secured and carries at its tree end, a roller 88 which is adapted to engage under a gear 2l so that at each complete revolution of gear 6, the gear 2l and its shaft 22 will be elevated to raise the Sponges and the dish above the level in tank 28. As it is necessary to raise the shaft 25 a distance greater than such movement imparted to shaft 22 in order to litt the upper sponge away from the plate, the following mechanism is provided: il coupling 89 is swiveled to the npper end or" shaft 25, and is connected to a cable 40. rl' his cable 40 is passed over pulleys 4l at the upper end ot an extension 42 on one ott the boards 8l. rlhis cable 40 is lsecured to one end of a sprocket chain 48, and said sprocket chain engages the outerv surface of a segmental sprocket cam 44. rfhe lower end ot said chain 48 is connected by a cable with a coupling 46 on the lower end or" shatt 22, and is passed under a pulley 47 on one ot the cross bars 8. lt will thus be seen that when the lower shaft 22 is elevated, that through the medium of the flexible connection above described, the upper. shalt 25 will be elevated, but the lmovement oit the upper shaft will be aug- "mented by the action ont the ratchet cam 44,

and will be caused to swing on its pivot, and hence compel the flexible chain 43 to bow outwardly which will increase the movement of shaft 25 sufficiently to allow a plate to be removed and replaced by another.

At one end ot the casing l, and to the sides thereof, plate guides are secured and incline so as to direct the plates downwardly into tank 28, but their downward movement is stopped by pins 49 which project into the path ot movement ot the plates. rllhese'lpins are carried by a transverse bar 50, which latter is provided at its ends with .downvardly projecting blocks 5ll which have dove-tailed mortise and tenon connection with guides 52 secured. to the walls or" the casing so that the vertical movement ot the bar and pins 49 is directed. Coiled springs 58 exert upward pressure on the blocks 5l to normally hold the pins 49 in elevated position, and these pins are drawn downwardly by longitudinally movable links 54. 'l'he links 54 have inclined slots 55 therein which receive pins 56 on blocks 5l, so that when the links 54 are moved to the right of ,Fig/l0, they will pull the pins 49 to allow a plate to move into the tank.

To the sides oi' casing l, and extendingl :trom the tank 28 to a platform 57 at one end of the casing, guides 58 are secured. These guides 58 support blocks 59, and the latter have tenons 60 which slide in the guides. The blocks 59 are secured to the lower ends of sprocket chains 6l, and are connected by coiled springs 62 with the end wall of 'tank 28 to normally hold 'the blocks in the posii,ovo,oia

tion shown in the drawings. rlhese blocks 59 are provided with beveled spring catches 68 which are adapted to engage the beveled ends 64 of links 54, so that when the blocks are moved toward platform 57, their first operation will be to move the links 54 in a direction to pull down pins 49. When these links 54 reach the limit of their movement, the spring catches G3 will ride otf the beveled end 64, and on the return movement will move into operative engagement as indicated because of the inherent elasticity of the spring catches.

The blocks 59 carry pivoted plate engaging fingers 65. These fingers 65 are preterably of rubber or surfaced with rubber, and at their tree ends are recessed to receive the edge of the plate in said recess. The iing'ers 65 are -free to swing in one direction, but movement in the opposite direction is prevented by contacting shoulders 66 as indicated in llig. 9. Springs 67 normally hold the fingers 65 in the position indicated and return them to such position after they have passed a plate on their return movement.

A movable carrier 68 is adapted to slide on the guides 58 and comprises a rectangular frame 69 preferably filled by a netting as indicated. .is preferably surfaced with rubber or other friction material to prevent any slipping of the plate when the latter is in position thereon. This bar 70, adjacent its ends, is provided with lugs 7l which move inside of the guides 58 and prevent lateral movement of the carrier.

The bar 70 on its upper tace, at its ends, is provided with hooks 72 which are adapted to engage small rollers 78 secured to casing l, and limit the outward movement of the carrier. rlhe chains 6l also pass under the rollers 73, and around segmental sprocket cams 74. rlhe outer ends ot these chains 6l are secured to cables 75 which pass around pulleys 76 and are secured to the upper transverse bar 28, so that when the shaft 25 is elevated, a longitudinal pull is had upon the chains 6l.

lt is, of course, to be understood that the operation is so timed that after a plate is washed, it will be elevated through the medium of the mechanism above described4v to a position above the level of the water in tank 28. This movement of the shafts 22 and 25 will exert a pull on the chains 61.

lhe iirst movement of the chains will draw the blocks 59 along the guides 58, so that the .ngers 65 will engage the plate 86 and torce the latter onto the carrier 68, the rubber faced bar 70 preventing any retrograde slipping of the plates. This movement of the blocks 59 also pulls the pins 49 downwardly to allow a plate on guide, 48 to fall into position on the lower sponge 24. As the chains 6l continue to draw outwardly,

ioo

invasie the blocks 59will engage bar 70, and move the carrier 68 outwardly. Due to the weight of the plate and also the weight of the carrier, the tree or outer edge of said carrier will move out onto the platform 57, such movement being limited bythe rollers 73 with which the hooks 72 come into contact. rl`he washed plate will then be in convenient reach for removal, and as thc apparatus continues to move, the springs 62 will return the parts to normal position. rlhe pivotal movement of the lingers will allow them to return to normal position, past the plate to be washed, because they pivot in a direction to allow such movement.

To compel the carrier to return to normal position, lugs 77 are provided on chains 6l which engage shoulders 78 on the end members of frame 69 as clearly shown in Fig. la.

TWhile we have referred to the cleaning devices as sponges, we would have it understood that the invention is not limited to Sponges, nor to any particular shape of plates, but the apparatus is capable of a wide range of usefulness, and various slight changes might be made in the general form and arrangement oi parts described without departing from our invention, and hence we do not limit ourselves to theprecise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
